>a vast field of manganese nodules [...] on the seabed in the Pacific Ocean
We've known for years that the seabed is full of easily extractable nodules containing various metals
Scraping the seabed has a long list of irreversible environmental consequences

- yread 2y agoThis area is on the order of 100km x 100km. There is a lot of sea floor out there. And 5km depth is not exactly brimming with life. If it can be used to replace substantial amount of fossil fuel consumption it would still come out as net positive.
- DemocracyFTW2 2y agoOTOH death by a thousand paper cuts is a thing. And frankly, that the exploitation could yield Japan's demand for 75 and 11 years only appears to be a 'long time' for types who don't see beyond quarterly bottom lines. It's one (high-output) country of 200, and we're talking about a decade and less than a century. How long until the fauna and flora of the seabed have recovered? One must also take into account that extraction will likely mean vast amounts of sands being upset, something that should almost never occur in the deep ocean except in case of an earthquake and also something that may affect areas far beyond the field proper.
